I have to admit it, and I think we all do it to some degree, which is letting a product's appearence cause us to either overlook it if not appealing, or buy it cuz it looks like it should be hanging from Buck Roger's belt. In walks the smok Tumbler tank, at first sight I though it was the ugliest thing I had ever seen. I mean have you seen this thing? Take a look at it in this Tumbler article if not. I remember sending links about it to friends to see if they agreed with me that the design engineers over at Smoktech were losing their minds, bowling pins? Really? Well recently I was given the chance to try one so I thought "sure, why not? Let's just put any lingering curiosity to bed and be done with it", so I loaded it up with some Boba's and took a nice long hit and to my surprise, I was impressed. It was smooth, flavorful, and produced a fair amount of vapor. So if you are put off by it's looks, and don't just take my word for it, read up on some reviews as well, and give it a try anyway. **Also, Kanger Protank/Evod universal coils will work in the Tumbler, but I have not tried a Smok coil in a Kanger.
